Problems solved by technology

However, the rapid expansion of the breeding scale and the non-standard breeding techniques have resulted in a variety of diseases in the cultured sea cucumbers. Among them, the auricular larvae in the nursery stage are prone to a kind of stomach wall thickening, roughness, blurred boundaries, and normal filling. The "rotten stomach disease", which is characterized by gradual shrinking, shrinking and deformation of the pear shape, has attracted great attention from the industry
The epidemic mainly broke out on the 5th to 7th day after the larvae were selected, and the prevalence was wide, resulting in high mortality of the larvae. There is no effective drug to control the development and spread of the disease, which often leads to the occurrence of the disease in sea cucumber nursery farms. No harvest

Embodiment 1

[0012] Purchase 2600 heads of ginseng from Shandong, with an average specification of 350-400g, and a temporary storage density of 7-10 heads / m 3 , Temporary water temperature is 15℃. When sea cucumbers are found to be excreted, immediately empty the pool water, dry and run the water, heat up to induce spawning and incubation. When the sea cucumber larvae develop to the late stage of the gastrointestinal stage, start to select the pool, and take samples every 2-3 hours to observe the esophagus. If the individual's esophagus is found to be slightly stretched, start to feed medical dry yeast tablets, each feeding amount is 1.5-2.5 tablets / m 3 , Adjust appropriately according to the feeding situation of the larvae; conduct sampling and microscopic examination of auricular larvae in all breeding ponds every morning. When the proportion of individuals with thickened and non-swelling stomach wall of sea cucumber auricularia larvae reaches more than 10%, 1h after feeding , Turn off the...

Embodiment 2

[0014] Purchase 1500 heads of ginseng from Changxing Island, Dalian, with an average specification of 300-350g, and a temporary storage density of 10-12 heads / m 3 , Temporary water temperature is 19℃. When sea cucumbers are found to be drained, they are moved to an empty pool for holding. When sea cucumbers are found to be ovulating, they are gently peeled from the pool wall and sent to the bottom of the pool. This time the seedlings are hatched by natural discharge and spawning. When the embryos of sea cucumber larvae develop to the early stage of small ear-shaped larvae, the appetite has not yet formed, the pool is selected, and the esophagus is sampled and microscopically observed every 2-3 hours. If the individual esophagus is found Slightly stretched, start to feed medical dry yeast flakes, each dose is 1.5-2.5 tablets / m 3 , Adjust appropriately according to the feeding situation of the larvae; conduct sampling and microscopic examination of auricular larvae in all breeding...

Abstract

The invention discloses a breeding method for effectively preventing and treating gastric ulcer diseases of auricularia larvae of sea cucumbers, and belongs to the technical field of aquaculture. When microscopic examination discovers that gastric walls of the auricularia larvae of the sea cucumbers are thickened and do not expand, the auricularia larvae are fed with medical dry yeast tablets for 1 hour, an oxygenation facility is switched off for 60-80 minutes, switched on for 20 minutes, switched off for 60-80 minutes and always switched on until the auricularia larvae are fed with baits for 1 hour next time, switch-on and switch-off of the oxygenation facility are circularly operated, and continuous oxygenation breeding is carried out until the microscopic examination discovers that the baits in gastric areas of the auricularia larvae are emptied and the gastric walls are thin and shiny and in full pear shapes. The breeding method for the sea cucumbers is simple and convenient, saves the breeding cost, and can effectively reduce the occurrence rate of the gastric ulcer diseases of the auricularia larvae of the sea cucumbers and stably provide good-quality fries, thereby having a relatively good application value.

Description

Technical field [0001] The invention belongs to the field of aquaculture, and specifically relates to a breeding method for effectively preventing and treating sea cucumber auricularia larvae gastrorotosis. Background technique [0002] The nutritional and medicinal value of sea cucumbers is high. With the progress of human civilization, the increase in demand and the limitation of natural resources, it has stimulated the vigorous development of its aquaculture industry. The scale of artificial seedlings and the rapid expansion of the breeding area have developed into my country in one fell swoop. The pillar industry of coastal aquaculture has significant economic and social benefits. However, the rapid expansion of the breeding scale and the non-standard breeding technology have caused many diseases in the cultured sea cucumbers. Among them, the ear-shaped larvae are prone to a kind of thickened and rough stomach wall during the nursery period, and the boundaries are blurred. Th...
